Is it true the freezing point of water is 100 C?
No, the freezing point of water is 0 degrees Celsius (32 degrees Fahrenheit). The boiling point of water is 100 degrees Celsius.
What is the freezing point of silly putty?
Silly Putty does not have a specific freezing point because it is not a true liquid that freezes, but rather a silicone polymer that hardens at low temperatures. Its properties can change depending on the temperature and environment it is in.
Which is true of a melting point and a boiling point?
A melting point is the temperature at which a substance changes from a solid to a liquid state, while a boiling point is the temperature at which a substance changes from a liquid to a gas. Both melting and boiling points are characteristic physical properties of a substance and can be used to identify and classify materials.
Describe the Beckmann's method for determining freezing point of so?
The Beckmann method involves adding a known mass of a solute to the solvent, measuring the freezing point depression caused by the solute, and using this data to calculate the molecular weight of the solute. By comparing the observed freezing point depression with the expected value, the true freezing point of the solvent can be accurately determined.
Which of the following is true about the melting point of potassium chloride?
The melting point of potassium chloride is relatively high, around 776 degrees Celsius. At this temperature, potassium chloride transitions from a solid to a liquid state.
True or False- The freezing point of a substance is equal to the melting point of a substance?
True. The freezing point of a substance is the temperature at which it changes from a liquid phase to a solid phase, while the melting point is the temperature at which it changes from a solid phase to a liquid phase. In equilibrium, the freezing point and melting point of a substance are the same.
What is true of the Celsius scale A. 212 is boiling point of water B. 0 is absolute sero C. 0 is the freezing point of water or D. 32 is the freezing point of water?
C. 0 is the freezing point of water.
What 2 processes will water undergo at 0 degrees Celsius?
Water's melting point is at 0oC. So going up in temperature starting from below zero, water melts. However, the opposite is also true. Instead of referring to it as a melting point, you can also call it the freezing point. So, going down from above 0oC, water begins to freeze.
Is it true the freezing point of water can be lowered with the addition of salt?
yea
Is 0 the freezing point of water?
Yes, it is true for Celsius scale.
Is it true the freezing point of water is 100 C?
No, the freezing point of water is 0 degrees Celsius (32 degrees Fahrenheit). The boiling point of water is 100 degrees Celsius.
Is freezing point of a substance is equal the melting point of the same substance?
Yes, the freezing point of a substance is the same as its melting point. This is because both processes involve a change in state from solid to liquid or vice versa, and the temperature at which this occurs is the same for a specific substance under constant pressure.
Would something freeze and melt at the same temperature?
This is a strange question. Water boils usually at 100 degrees Celsius and freezes at 0 degrees Celsius. Who understands this question? I think you mean "If a substance changes from solid to liquid when the temperature exceeds 100 degrees, will it change from liquid back to solid when cooled to below 100?" Yes, it will.
True or false the freezing point of water can be lowered with the addition of salt?
True - adding salt to water lowers its freezing point. This occurs because the presence of salt disrupts the formation of ice crystals, requiring lower temperatures for the water to freeze.
A wet rock generally melts at a lower temperature than a dry rock true or false?
True. Water has a lower melting point than most rocks, so when a rock is wet, the presence of water can lower the overall melting point of the rock.
True or false the difference between water freezing and water boiling in the Fahrenheit scale is 100?
False because the difference between it is 180
Why does steric acid freeze and melt at the same temperature?
Both melting point and freezing point define the temperature at which a material changes either from a solid to a liquid or a liquid to a solid. A material freezing or melting is the same just the reverse so they happen at the same temperature. This is sometimes not true when you get supercooling or superheating, but that is more complicated!
